Abstract

PURPOSE:To provide an automatic program controller which can surely and previously control the control data of the decided time on the undecided time without requiring any manual operation even if (n) pieces or more of control data on the undecided time are continuous. CONSTITUTION:A search task 22-1 of a task group 2-i is started when the next control data that undergoes the collation processing by a collation processing task 21-i is identical with the control data on the undecided time. Then the task 22-i searches the control data on the undecided time that is set just after the continuous control data on the undecided time and then stores the point of the searched control data into a common information area 32 of a main storage 3. If the control data are included within the maximum previous control timing ahead of the point control data stored in the area 32, the task 22-i stores the number (m) of pieces of control data in the area 32.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic program control device, and more particularly to a pre-standby control method for the automatic program control device.

[0002]

2. Description of the Related Art Conventionally, as a control method in an automatic program control device (APS), a method of performing control by collating control data at a fixed time when the broadcast time is fixed with the current time (hereinafter, this control will be described). Real-time control) and a method to control the control data of the uncertain time when the broadcasting time is uncertain by using the trigger signal from the outside to check the control data by comparing it with the asynchronous current time. There is and).

The automatic program control device controls the external peripheral device for storing the program content and the like at one or a plurality of timings by the real-time control and the untimed control.

In the automatic program control device, the control data at the fixed time and the control data at the unfixed time are stored in the order in which the programs controlled by them are broadcast, and the next control data is the control at the fixed time. If it is data, real-time control is performed, and if it is control data at an indefinite time, untime control is performed.

Regarding the control data at the uncertain time, if the next control data is the control data at the uncertain time,
The uncertain time is set to the fixed time by the trigger signal from the outside.

In this case, an asynchronous pulse output request is made to the timepiece device at the determined time, and thereafter, the asynchronous pulse from the timepiece device is counted for a required period to obtain the asynchronous time. The matching process is performed in the same manner as the control data.

In the above automatic program control device, it is necessary to complete the collation process and the control output process within one second with one interruption from the timepiece device. It is designed to refer to control data (a positive integer).

Further, even if there is control data with an indefinite time after the next control data, if there is control data with a definite time within n pieces, it is possible to perform pre-control on them. Therefore, even if the automatic program control device does not receive a trigger signal from the outside, if the current time and the time of the control data of the fixed time match, the function of automatically skipping the control data of the unfixed indefinite time, That is, it has a function of skipping the control data of the undetermined undetermined time, extracting the control data of the undetermined time, and performing control.

Thereafter, in the same manner as the above-mentioned processing, if the control data is the control data at the fixed time, the automatic program control device controls so that the video and audio corresponding to the fixed time will flow, and the control data becomes the undefined time. If the control data is, the control data at the indefinite time is confirmed in response to the trigger signal, and control is performed so that the video and audio corresponding to that time flow.

[0010]

In the above-mentioned conventional automatic program control device, since n control data after the next control data are referred to, n or more uncertain time points after the next control data. If the control data of the fixed time exists, the control data of the fixed time cannot be referred to even if the control data of the fixed time exists after the control data of the unfixed time.

For this reason, it is not possible to perform pre-control for the control data at the fixed time and skip the control data at the unfixed unfixed time even at that time. In order to deal with this problem, in the conventional automatic program control device, the operator must perform a manual operation such as deleting the control data of the uncertain time when the control data of the uncertain time becomes unnecessary. .

Therefore, the object of the present invention is to solve the above-mentioned problems, and to perform advance control for the control data at the fixed time without performing a manual operation even when the control data at the unfixed time is continuous for n or more. An object of the present invention is to provide an automatic program control device that can be reliably performed.

FIG. 2 is a diagram showing the processing operation of the search task 22-i of FIG. In the figure, U indicates control data at an indeterminate time, and R indicates control data at an indeterminate time. When the search task 22-i searches the control data at the fixed time existing immediately after the control data at the undefined time that continues at the point a, the data number m of the control data within the point a and the maximum pre-control timing is the common information area. Three
Stored in 2.

FIG. 3 is a flowchart showing the processing operation of the matching processing task 21-i of FIG. 1, and FIG. 4 is a flowchart showing the processing operation of the search task 22-i of FIG. The operation of the embodiment of the present invention will be described with reference to FIGS.

The collation processing task 21-i refers to n pieces (n is a positive integer) of control data when one interruption is started from the timepiece device 1.

That is, when the collation processing task 21-i is activated by an interrupt from the timepiece device 1, the reference number l is initialized (step S1 in FIG. 3) and the next control data is the control data (U ) Or not (step S2 in FIG. 3).

The collation processing task 21-i leaves the uncertain time flag (U flag) at the initial value ("0") unless the next control data is the control data at the uncertain time (FIG. 3).
Step S3).

If the next control data is the control data at the uncertain time, the collation processing task 21-i activates the search task 22-i (step S4 in FIG. 3) and sets the U flag to "1". (FIG. 3 step S5).

The collation processing task 21-i refers to the next control data, creates a control code, performs pre-control on the next control data (step S6 in FIG. 3), and counts up the reference number 1 ( 3 steps S7 and S8).

The collation processing task 21-i determines whether or not the reference number l is larger than the number n of days of the control data to be referred to by the count-up (step S9 in FIG. 3), and the n control data. The above process is repeated until the above is referred to.

The search task 22-i is the collation processing task 2
When activated by 1-i, it sends the next control data to APS.
It is read from the data area 31 and referred to (see step S2 in FIG. 4).
1) It is determined whether the control data is the control data (R) at the fixed time (step S22 in FIG. 4).

The search task 22-i repeats the above processing until the control data read from the APS data area 31 becomes the control data at the fixed time, and when the control data to be referenced becomes the control data at the fixed time, the control data becomes the control data. The point a of the control data at the fixed time is stored in the common information area 32 (step S23 in FIG. 4).

Next, the search task 22-i calculates the number m of control data within the maximum advance control timing (+ x seconds) from the point a (step S2 in FIG. 4).
4). The search task 22-i stores the calculated data number m in the common information area 32 (step S23 in FIG. 4), and ends the processing.

The collation processing task 21-i refers to the n pieces of control data and determines whether or not the U flag is set to "1" (step S10 in FIG. 3). "1" in U flag
If is not set, the collation processing task 21-i ends the processing.

If "1" is set in the U flag,
The collation processing task 21-i determines whether or not there is control data at the confirmed time among the n control data referred to (step S11 in FIG. 3).

If there is control data at the fixed time among the n control data referred to, the collation processing task 21-i controls the point a searched by the search task 22-i among the n control data. It is determined whether or not there are m control data after the data (step S12 in FIG. 3).

If there is no control data at the fixed time among the n control data referred to, the collation processing task 21-i sets the point a searched by the search task 22-i as the reference point (step S13 in FIG. 3). ).

Thereafter, the collation processing task 21-i sets the U flag to the initial value "0" (step S14 in FIG. 3),
The number m of data searched by the search task 22-i is set to the number n of data to be referred to (step S15 in FIG. 3).

As a result, the collation processing task 21-i starts to refer to the m control data after the control data of the point a searched by the search task 22-i, and stores the reference result in the common information area 32. .

The collation processing task 21-i determines that there are m control data after the control data of the point a searched by the search task 22-i among the n control data referred to, or the point a M after the control data of
When the individual control data are referred to, the processing is ended.

As described above, when the next control data is the control data of the uncertain time, the point a of the control data of the uncertain time existing immediately after the group of control data of the uncertain time is searched by the search task 22-i. By searching the number m of control data within the maximum pre-control timing from the point a, even if the control data at uncertain times continues for n or more, the group of control data at uncertain times can be It is possible to surely perform the pre-control for the control data at the finalized time that immediately follows, and also surely perform the pre-control for the control data within the maximum prior control timing subsequent to the control data at the finalized time.

Therefore, even when the control data at the uncertain time is continuous for n or more, it is possible to surely perform the pre-control for the control data at the confirmed time without performing a manual operation.

[0047]

As described above, according to the present invention, when the fixed time data following the undefined time data is extracted and the extracted fixed time data is searched for a predetermined number of control data set in advance, When it is detected that it does not exist in the predetermined number of control data, a specific number of fixed time data following the fixed time data is searched and retained, so that n or more control data of uncertain time are consecutive. There is an effect that the pre-control for the control data at the fixed time can be surely performed without performing the manual operation even when the vehicle is in the open state.
